>>87230834Some of this I think is because you're doing latent upscale in hires fix? I'm not using the exact same model as you so the image is obviously different but I just copied your prompt and tried with/without that step and at least to me the upscaled one looks a bit more washed out.
Also this part is probably not related to the colours but you don't need that many sampling steps, you can probably drop it down a bit and gen a little faster
